ATM cell multiplexer and scheduling method therefor

An ATM cell multiplexer comprising:

• a plurality of cell assemblers/disassemblers having at least one connection;
• a table manager for setting a schedule table having transmission time information, which is allocated to each cell assembler/disassembler based on the number of said cell assemblers/disassemblers, the number of said at least one connection, and the traffic volume of said at least one connection;
• and
• a controller for controlling said transmission time in each cell assembler/disassembler according to said schedule table,
• wherein said table manager produces said schedule table by preparing a unit table in which the number of time slots assigned to the schedule table is divided equally by the maximum number of cell assemblers/disassemblers that can be mounted, storing a transmission pattern table having said transmission time information corresponding to a plurality of traffic volumes, extracting a transmission pattern table corresponding to the traffic volume of the connection of each cell assembler/disassember, and applying a transmission pattern table corresponding to each cell assembler/disassembler to a unit table corresponding to each cell assembler/disassembler.

A scheduling method of an ATM cell multiplexer comprising a plurality of cell assemblers/disassemblers having at least one connection comprising the steps of:

• setting a schedule table having transmission time information, which is allocated to each cell assembler/disassembler based on the number of cell assemblers/disassemblers, and the number of connections, and the traffic volume of the connections;
• and
• controlling said transmission time in each cell assembler/disassembler in accordance with the schedule table,
• wherein schedule table corresponding to all the communications patterns determined based on the number of cell assemblers/disassemblers, number of connections, and said traffic volume are prepared, and said schedule table corresponding to a set communications pattern is extracted therefrom in said setting step.

A scheduling method of an ATE cell multiplexer comprising a plurality of cell assemblers/disassemblers having at least one connection comprising the steps of:

• setting a schedule table having transmission time information, which is allocated to each cell assembler/disassembler based on the number of cell assemblers/disassemblers, and the number of connections, and the traffic volume of the connections;
• and
• controlling said transmission time in each cell assembler/disassembler in accordance with the schedule table,
• wherein said schedule table is produced in setting step by preparing a unit table in which the number of time slots assigned to the schedule table is divided equally by the maximum number of cell assemblers/disassemblers that can be mounted, storing a transmission pattern table having said transmission time information corresponding to a plurality of traffic volumes, extracting a transmission pattern table corresponding to the traffic volume of the connection of each cell assembler/disassembler, and applying a transmission pattern table corresponding to each cell assembler/disassembler to a unit table corresponding to each cell assembler/disassembler.
